Comprehensive genomic and functional characterization of a phytoplasma associated with root retardation, early bolting, witches’-broom, and phyllody in daikon (Raphanus sativus L.) [PDF]

Frontiers in Microbiology
Daikon (Raphanus sativus L. var. longipinnatus) is an economically important root crop and medicinal plant. In 2021, a previously unreported disease outbreak characterized by early bolting, witches’-broom, phyllody, virescence, and severe root growth ...

The Rosa chinensis cv. Viridiflora Phyllody Phenotype Is Associated with Misexpression of Flower Organ Identity Genes

Frontiers in Plant Science, 2016
Phyllody is a flower abnormality in which leaf-like structures replace flower organs in all whorls. Here we investigated the origin and the molecular mechanism of phyllody phenotype in Rosa chinensis cv.

Potential mobile units drive the horizontal transfer of phytoplasma effector phyllogen genes [PDF]

Frontiers in Genetics, 2023
Phytoplasmas are obligate intracellular plant pathogenic bacteria that can induce phyllody, which is a type of abnormal floral organ development. Phytoplasmas possess phyllogens, which are effector proteins that cause phyllody in plants.

Comparative DNA Methylome of Phytoplasma Associated Retrograde Metamorphosis in Sesame (Sesamum indicum L.) [PDF]

Biology, 2022
Phytoplasma-associated diseases such as phyllody and little leaf are critical threats to sesame cultivation worldwide. The mechanism of the dramatic conversion of flowers to leafy structures leading to yield losses and the drastic reduction in leaf size ...

Multigene analysis reveals ‘Candidatus Phytoplasma asiaticum’ (16SrII-C) association with niger and sesame phyllody in Madhya Pradesh, Central India and identification of a putative vector [PDF]

Frontiers in Plant Science
A field investigation was conducted during the winter seasons of 2021–22 and 2022–23 at the Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur, Central India, to identify and characterize the phytoplasma strains associated with niger (var.

Detection, Identification and Molecular Characterization of the 16SrII-V Subgroup Phytoplasma Strain Associated with Pisum sativum and Parthenium hysterophorus L. [PDF]

Plants, 2023
Two unrelated plant species, green pea and parthenium weed, harboring typical phytoplasma symptoms, were discovered in Yunlin, Taiwan. Green pea (Pisum sativum.) and parthenium weed (Parthenium hysterophorus L.) are both herbaceous annual plants ...

Differential Symptomology, Susceptibility, and Titer Dynamics Manifested by Phytoplasma-Infected Periwinkle and Tomato Plants [PDF]

Plants
Phytoplasmas are intracellular pathogenic bacteria that infect a wide range of plant species, including agriculturally important crops and ornamental trees. However, our understanding of the relationship between symptom severity, disease progression, and

Random mutagenesis-based screening of the interface of phyllogen, a bacterial phyllody-inducing effector, for interaction with plant MADS-box proteins [PDF]

Frontiers in Plant Science, 2023
To understand protein function deeply, it is important to identify how it interacts physically with its target. Phyllogen is a phyllody-inducing effector that interacts with the K domain of plant MADS-box transcription factors (MTFs), which is followed ...
